(anc. geog.) a town of Latium, pleasantly situated on the Anio. Here Horace had his villa and house; and here he wished to end his days. Here Adrian built an extraordinary villa called Tiburtina, inscribed with the names of the provinces and of the most considerable places, (Spartian); near which Zenobia had a house called Zenobia, (I' rebellius, Pollio). Hither Augustus often retreated on account of its salubrity, (Suetonius): for which it is greatly commended, (Martial). Anciently, when the Romans had far extended their territory, it was the utmost place of banishment, (Ovid). It had a temple of Hercules; and therefore called Herculeum. In the temple was a library, (A. Gellius). Now Tivoli in the Campagna di Roma on the Teverone.
